Brief data summary

scan listing

M band (6 GHz) network monitoring experiment, observed on 6th June 2006. Data rate was 128 Mbps (16 X 2 MHz subbands, dual polarization, two-bit sampling). The target source was '1222+037'. 3C273B was also observed as a calibrator.
9 stations participated. Torun showed fringes in the (OH 6035 MHz) pass until 0days 21:15 UT when it was off-source for an RF filter change. It was then lost to a power supply failure until 21:44 but was OK after that time. Noto displayed weak fringes in the second pass (OH 6035 MHz). All other stations showed fringes.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.97 . ERI* = 0.97 .
(MC=1, ON=1, WB=1, HB=1, TR=0.7, EF=1, NT=1, JB=1, CM=1)
Plots of the autocorrelations
Comments.
These plots show the problem with Darnhall, high total power in 'IF7 and IF8' in the terminology of these plots. Please see the NME report at ftp://ftp.jive.nl/monitor/n06m2.ps.
plots of the uncalibrated amplitude and phase

Comments.
Noto fringes are weak.
Plots of the uncalibrated amplitude and phase
against frequency channel
Comments.
Da shows high flux in IF7 and IF8 (RR \& LL). Wb shows low flux in IF1 and IF2 in RR polarisation only throughout the second pass. Jb has low flux in IF 3 and IF 4 (LL only). On has very low flux in IF 3 and IF 4 (LL only).

Comments.
Da shows high flux in IF7 and IF8 (RR \& LL).
TSYS against time
Comments.
Telescope sensitivities
from the a priori TSYS and Gain
curves (the square of this number gives the antenna noise (SEFD) in Jy - the
smaller the better).
Comments.
Fringe-fit phase solutions
(including Parallactic
Angle correction).
Comments.
Hh had a vey fast phase rate initially.

Telescope bandpasses
Comments.
Jb, Nt, Hh missing IFs due to low bandpass fluxes.
Calibrated amplitude and phase against time
(a
priori amplitude calibration and fringe-fit solutions applied).
Comments.
Hh, Da, Nt have bad amplitude calibration.
